A Compact Extreme Scattering Event Cloud Towards AO 0235+164
C. E. Senkbeil, S. P. Ellingsen, J. E. J. Lovell +3
We present observations of a rare, rapid, high amplitude Extreme Scattering Event toward the compact BL-Lac AO 0235+164 at 6.65 GHz. The ESE cloud is compact; we estimate its diame…
How do methanol masers manage to appear in the youngest star vicinities and isolated molecular clumps?
A. M. Sobolev, D. M. Cragg, S. P. Ellingsen +10
General characteristics of methanol (CH3OH) maser emission are summarized. It is shown that methanol maser sources are concentrated in the spiral arms. Most of the methanol maser s…
Investigating high-mass star formation through maser surveys
S. P. Ellingsen, M. A. Voronkov, D. M. Cragg +3
Interstellar masers are unique probes of the environments in which they arise. In studies of high-mass star formation their primary function has been as signposts of these regions…
The Australia Telescope campaign to study southern class I methanol masers
M. A. Voronkov, K. J. Brooks, A. M. Sobolev +3
The Australia Telescope Compact Array (ATCA) and the Mopra facility have been used to search for new southern class I methanol masers at 9.9, 25 (J=5) and 104 GHz, which are though…
A search for 22-GHz water masers within the giant molecular cloud associated with RCW106
S. L. Breen, S. P. Ellingsen, M. Johnston-Hollitt +7
We report the results of a blind search for 22-GHz water masers in two regions, covering approximately half a square degree, within the giant molecular cloud associated with RCW 10…
A GLIMPSE-based search for 6.7-GHz Methanol Masers and the lifetime of their spectral features
S. P. Ellingsen
The University of Tasmania Mt Pleasant 26-m and Ceduna 30-m radio telescopes have been used to search for 6.7-GHz class II methanol masers towards two hundred GLIMPSE sources. The…
